Therefore, the workstations 201, 202, and 203 under the communication range of the base station 205 can access the data on the wired network 106 through the base station 205, such as the server 206 shown in FIG. 2, which can be File servers, mail servers, and web servers. Each of the workstations 201, 202, and 203 can also be connected to the Internet 107 through the base station 205 through the gateway 105 on the wired network 106. Next, the method for improving the wireless local area network transmission efficiency of the system of the above embodiment will be described, which includes a procedure for establishing a wireless local area network neighbor and a procedure for establishing a high-efficiency transmission mode. Please refer to Fig. 3 and Fig. 4 to describe the procedure for establishing a wireless local area network neighbor. First, referring to FIG. 3, the first workstation 2 0j assigns a media access control address (MAC address), an Internet address (internet pr0t〇c0, address' IP address), and Host name (h〇stname), etc.

Relevant information is packaged into transmission packets of lower-level network protocols, such as media access control packets (MAC access control packets).

Then set Λ chronograph 3 02 ′ to calculate the waiting time when the response time exceeds the long waiting time, which is the time-out, and the action of establishing a local area network neighborhood. If you are still coming and ... the establishment is not ^ ^, the right direction has not timed out, then wait for the establishment neighbor corresponding to the establishment neighbor Mingqiu 301 to respond 406 (as in the second station 202, 203 party. Tian Yu's order The action is the same, 589841 V. Description of the invention (7) 'Therefore, the following description will only be made with the second workstation 002. f extra reference _, when the first station 202 receives a network packet 401 (34〇1) First, determine whether the network block 401 is a neighbor establishment request (S4〇2), and continue from the previous example, that is, a neighbor establishment request 301. If it is not a neighbor establishment request 3001, it will be processed by IEee 802 · lib standard procedure. The received network packet 401 (§ 403). In order to establish a neighbor relationship request 301, the relevant information of the workstation 201 is extracted from the neighbor relationship request 3101, that is, the MAC address, the lp address, and the host name. = j04). After that, the second workstation 200 obtains relevant information of itself,

MjC address, 1? Address and host name (S405), and return a neighbor establishment response 406 (S406) corresponding to the neighbor establishment request 301, which contains the relevant information of the first station 201 And related information of the second workstation 200. Referring to FIG. 3 again, the first workstation 201 is waiting for the neighbor establishment response (S303), receives the neighbor establishment response 406, and first determines whether or not the neighbor establishment response 1 is a new neighbor establishment response (S304). If it is not a new response, a station continues to wait for a neighbor response until it times out (S303). For the new response, the first workstation 201 extracts information from the neighbor establishment response 406, and the second workstation 202 receives relevant information, namely, the MAC address' IP address and host name (S30 5). Finally, the first workstation 201 can establish a wireless local area network neighbor connection with the second workstation 202 as required. Next, the procedure for establishing a high-efficiency transmission mode will be described with reference to Figs. 5 and 6. Referring to FIG. 5, the first workstation 201 first selects at least one second workstation (S501) that receives data from the wireless LAN list, and extends the second example, that is, the workstations designated as 202 and 203. Since the actions performed by 203 on the second workstation 2002 are the same, the following will only be described with the second workstation 2022. 589841 V. Description of the invention (8). After that, the 工作站 -workstation 201 sends a setup high-efficiency transmission 502, and asks whether the second workstation 002 is willing to set up: Yu 'find the line (S502), and then waits for a corresponding response (S503). Modes link the actions of establishing a high-efficiency transmission mode. If it is overtime, please refer to FIG. 6 'After receiving the ancient request 502 (S601), the second workstation 202 may request the first workstation 202: 6.2, for example, using Mimar in the conventional technology. OR key: authority 'to decide whether to agree to establish a high-efficiency transmission mode or (S602). If the first station 001 is required to provide verification information, it must issue a request for verification information 6 03 (S603), and then respond to 'then should (S604). If it expires, end the establishment of a high-efficiency transmission mode corresponding response. The first workstation 201 is waiting for the establishment of a high-efficiency transmission mode response, (S503). As it is judged that the response it receives is a request for verification data ~ 6y (S504), as shown in FIG. 5, so the step C returns a request- Beixun responded with 505, which contained the necessary verification information 602 to pass: The verification of Workstation 202. After the second workstation 200 receives the verification information 602, one is correct (S605). If it is not correct, then go back to step =: ΐί; ίϊι =: / Λ6 ° 3 ’Explain its verification information. Workstation 201 will provide verification information 602 for a long time. Sign a workstation 20 / re-execute step S505 and return the request for verification information in response to the "right verification information 6 02" is correct, the second workstation 202 will return to the construction mode and respond 6. 6 'agree to establish a high-efficiency transmission mode After receiving the response 606 of the establishment of a high-efficiency transmission mode, the first station 201 of the first station 201 scans the available frequency f on a limited legal frequency band after the first station 201 scans the available frequency f in a limited legal frequency band. Avoid collision and interference of transmission. For example, IEEE 802 · lib specifies at least three frequency bands. Taking North American standards as an example, the center frequencies of the three frequency bands are 2412 MHz, 2437 MHz, and 2462 MHz. The first workstation 201 can scan these three frequency bands, avoiding the frequency currently used by the base station 205 or other interference frequencies, so as to avoid transmission collision or interference. In addition, a set of service set identifiers (dUervice set identifiers, SSIDs) are randomly generated for use as a certificate with the second workstation 202. The first workstation 201 informs the second workstation 202 of the frequency f and the service set identification (S50 6). After that, the first workstation 205 and 205 reported that it switched to the power saving mode s (p〇wer “化 化 化”), and changed the transmission mode to the point-to-point mode, and set the factory efficiency to 202 with the frequency f ′. Connection in transmission mode (s507). It should be noted that if the wireless local area network 201 and the second workstation 202 can be paired with two early mornings, the step _ will be performed after the first workstation ′ to establish a high: === 6. The first workstation 201, after receiving the effective sheep pass = cut 606, proceeds to step S506, scans the door, and responds to the loss mode by identifying and drinking d, and notifying the second workstation m. After receiving the frequency f, the second workstation 2002 of the generating service set extracts this information (S607), the information such as the identification code d is switched to the power saving mode, and the transmission is reported to the C station 205 to report its rate f and service set identification code d wait for the first two, ，,, point-to-point mode, and frequency. ”Workstation 201 directly establishes high efficiency. Page 16 V. Description of the invention (10) Rate transmission mode connection to transmit data ( S608). The first workstation 2 〇1 calculates the timeout period during the resumption timer (s_ repeated period, you can set an action to set up a high-efficiency transmission mode); if it fails, end the package and package data In contrast to the second workstation 2. Successful encapsulation, the first-industrial spit 9η9 shiyi "point-to-point transmission (S5 09) After 0, the connection is established in the high-efficiency transmission mode and the successful data transmission is dr; packet-encapsulated data (s_.

After the first job and the second pass, you can retrieve the temporarily stored data on the base station 205. For those who need attention, the first workstation asks whether the second workstation would like to build: When the effect = output mode is connected, the second station must receive a response T. To establish a high-efficiency transmission mode is to include the information from all the second stations that the first station can listen to. =, As shown in Figure 2, suppose workstation 204 is in the range of the first workstation 2001, 2G1R, you can hear the inquiry of workstation _2 () 1, that is, the same efficiency transmission mode request 5 is caught 2. However, the workstation 204 may have too much environmental interference, and the effective communication range 204R is therefore small, so that = the establishment of a high-efficiency transmission mode response 6 issued by the station 2 0 4 could not be accepted by the first station 201 Heard, so the first workstation 201 and the workstation,

P.17 589841 V. Description of the invention (π) 204 Although both are within the communication range 205R of the same base station 205, the first workstation 201 still cannot establish a high-efficiency transmission mode connection with the workstation 204. In addition, a high-efficiency transmission is established. The security settings when transmitting data in mode connection also follow the settings of the original wireless LAN communication standard. For example, the Wired Equivalent Privacy (WEP) method is used to encrypt the transmission data. Since it belongs to the same base station, the keys used by WEP are necessarily the same, so there is no need to consider the authentication point-to-point of authentication. The stream can also be used to transmit frequency and interference. In addition, the base station data will be used to retrieve the technology without losing the wired network access data according to the development mode. The base station will temporarily suspend wireless data. Any of the temporarily stored data mentioned above can be separated from its savvy embodiment of the conventional data transmission technology, which can be used in a point-to-point mode to improve the frequency of stations that can be used to save to the high-efficiency local network. Work station information, not just for illustrative purposes based on the above nature and scope. ’Then cooperate with the video to ensure the data transmission of video products, to establish the bandwidth used. The rate is different. When the transfer mode data in the electrical mode is separated from the transmission mode, the connection with the network will be interrupted. The implementation of the invention is not limited. For example, the working stream (vide 〇 quality) in the local network. A large number of high-efficiency transmission modes and the data between the workstations to avoid the phase of the two stations and the base station's data also includes the Internet, the workstation can be the connection between the Internet. Any implementation of the equivalent is the station Interconnections that can be transmitted using wide-band connections between stations, because these networks are transmitted to the base.
